Great add-on Rated 3 out of 5 stars
I like the add-on a lot, my only problem with it is that it forces the Add-on Bar to display, even if I disable the Add-on Bar.
I would like a future update to include an option to NOT display this in the Add-on Bar (thus removing the problem) or just not even listing in there to begin with. I have disabled the app for now as I cannot stand Xing out of the Add-on Bar upon every new instance of Firefox that I run.
Apologies for taking such a long time to fix the problem but it is now fixed. Installing version 2.5.1 will make the add-on bar respect your wishes as to whether or not it appears.
